AAT3218  
150mA MicroPower™ High Performance LDO  
PowerLinear  
General Description  
Features  
The AAT3218 MicroPower low dropout linear regula-  
tor is ideally suited for portable applications where  
very fast transient response, extended battery life,  
and small size are critical. The AAT3218 has been  
specifically designed for high-speed turn-on and turn-  
off performance, fast transient response, and good  
power supply ripple rejection (PSRR), and is reason-  
ably low noise, making it ideal for powering sensitive  
circuits with fast switching requirements.  
Low Dropout: 200mV at 150mA  
Guaranteed 150mA Output  
High Accuracy: ±1.5%  
70µA Quiescent Current  
Fast Line and Load Transient Response  
High-Speed Device Turn-On and Shutdown  
High Power Supply Ripple Rejection  
Low Self Noise  
Short-Circuit and Over-Temperature  
Protection  
Uses Low Equivalent Series Resistance  
(ESR) Ceramic Capacitors  
Output Noise Reduction Bypass Capacitor  
Shutdown Mode for Longer Battery Life  
Low Temperature Coefficient  
Other features include low quiescent current, typical-  
ly 70µA, and low dropout voltage, typically less than  
200mV at the maximum output current level of  
150mA. The device is output short-circuit protected  
and has a thermal shutdown circuit for additional pro-  
tection under extreme operating conditions.  
16 Factory-Programmed Output Voltages  
SOT23 5-Pin or SC70JW 8-Pin Package  
The AAT3218 also features a low-power shutdown  
mode for extended battery life. A reference bypass  
pin has been provided to improve PSRR perform-  
ance and output noise, by connecting a small  
external capacitor from device reference output to  
ground.  
Applications  
The AAT3218 is available in a Pb-free, space-sav-  
ing 5-pin SOT23 or 8-pin SC70JW package in 16  
factory-programmed voltages: 1.2V, 1.4V, 1.5V,  
1.8V, 1.9V, 2.0V, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V,  
2.85V, 2.9V, 3.0V, 3.3V, or 3.5V.
